Physical properties -can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter.
A chemical property -is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected for its chemical properties to be investigated.
Physical change-any process involving a substance's change from one state (gas, liquid, solid) to another without alteration of the chemical composition; cf.chemical changeany change from one state (gas, liquid, solid) which is accompanied by alteration of the chemical composition; any process in which one or more substances are changed into one or more different
Chemical Reaction- Compare nuclear reaction a process that involves changes in the structure and energy content of atoms, molecules,orions but not their nuclei
